BARGE-PUMP.

SPECIFICATION forming part of `Letters Patent No. 255,492, dated March 28, 1882.

' Application tiled May 23, 1881. (No model.)

To all whom @t may concern Be it known that we, JACKSON D. GOWAN and ROBERT E. LEE, of McKeesport, in the co'uiity of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Barge-Pumps; and we do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the saine, reference being had to the accompanying drawings, which form a part ot' this specification.

This invention relates to an improved construction of what are knows as barge-pumps7 that is, a short pump provided with acheckvalve at its foot, a sucker-rod or spear a bucket, and an overhanging spout-the pump being used by placing it in the well or other portion ot' the barge or other craft with the spoilt projecting over the edge of the barge, so that the water pumped will fall clear ofthe saine. These pumps are made of wood, and are therefore wanting in durability, and, being ot' wood, are very troublesome and difficult to keep tight and in'work-ing order. V

Ourinvention consists in making the pump body or barrel of seamless iron tubing, and in providing the saine with a suitable spout to discharge the water. Further, in constructing the pump with a detachablecheck-valve or clack-valve and valve-seat, whereby the il'exible valve used maybe readily replaced when worn out; and, further, in the construction and combination of parts, substantially as hereinafter described and claimed.

In the drawings, Figure lis al side elevation of our improved barge-pump. Fig. 2 is a vertical section ot' the same. Fig. 3 is a top view. Fig. 4 is a top view of the valve and valveseat, half ofthe valve being removed. Fig. 5 is a transverse vertical section of Fig. 4.

The barrel or body A is a single'piece of seamless wrought-iron tubing, and may be ot' the kinds known as lapweldor butt-weld.77 This at the bottom is formed with a leg, a, which, while supporting the puinp, allows free access of water thereto in the well of` the craft. At its top, barrel A is threaded exteriorly and screwed intov a threaded casting, B, of square form at the top, as shown vat Fig. 3. To casting B are screwed the spout-jaws b b and back c,

and between jaws b b the apron dis secured by nailing through jaws b I).

We thus construct a barrel and spout in an exceedingly cheap and simple manner, and .produce a pump ot' great durability and strength, while retaining sufficient lightness for convenient and easy handling. It' let't for an indeinite time-in the sun, the barrel cannot warp and crack and become leaky, as a wooden barrel does. Besides,the small space occupied by the walls of the barrel enables us to increase the diameter without enlarging the exterior, and we thus can increase the capacity.

The usual sucker-rod or spear and bucket are used for operating.

The clack valve and seat at the foot are peculiar. The seat consists of an annular casting, F, having the cross-bar j'. The upper face lot' the casting F is ground or turned true, or

reasonably true. Two bolt-holes, g, are either cored oi bored vertically through the crossbarf or through diametrically-opposite points inthe casting F. This casting is made slightly larger than the bore ot' barrel A. Then the latter is heated, and thus expanded,when`the cold castingF is inserted, so that upon cooling the barrel A shrinks upon and permanently retains the casting F in proper position.

The valve consists of a circular piece, s, ot' leather, rubber, or other appropriate flexible material, to which are riveted on top the nearly seinicircular plates t, ofiron, or Zinc, or galvanized plate, or copper. The valve has holes of a. diainetercorresponding to thelioles g in crossbar f. A cap-bar, ll., having bolts i, is placed across the valve between the plates t, with bolts i passing down through the valve s. Thus constructed, the valve is folded up and inserted upwardly through the castiiigf, and arranged so that the bolts fi drop down in holes g, after 'which all is readily secured by the nuts lr. The

placing or removing of the valve is done in a few inoments,sotliat when worn outthe leather may be readily removed. y

Vhile we have shown and described a particular form ot' spoilt and manner of attachnient ofthe saine, we do not contne ourselves herein to such form, as it may be varied without departing from the spiritot our invention.

We claiml. In a barge-pu mp, a cylindrical barrel con- ICO sisting of seamless' wrought-iron tubing, in our own we have hereto axed our sgnaturs combination with a. detachablel cast-iron ha in presence of two witnesses. and wooden spout, substantial yas descri e f 2. The combination specically of the cy- IQWAN 5 lindrical barrel A of iron tubing, the casting l B, Wooden jaws b b, back c, and apron d, sub- Witnesses: stantially as described. F. J. PATTERSON,
